Is this 2 of the ESP32 chips?

The products you will get are 2 x ESP32 Development Board, just like the first picture shows.

Does anyone use this with wled sound reactive firmware and max4466? could really use your help with the pins setup. thx!

Get a board with better support. The pinout is wrong on this board so finding support for projects is nearly impossible.

Where is a schematic? need to understand why some gpio pins don't work as expected. p0 and p19 don't work, p2 works but has an on-board blue led.

The PCB's silkscreen gpio is labeled different from the physical on-board gpio of the chip.

Has anyone had any luck getting micropython onto this board?

Yes. Search for "Firmware for Generic ESP32 module" (URLs not allowed here). Download esp32-20210418-v1.15.bin from list under "Firmware with ESP-IDF v4.x"
